摘要:In this paper, the selective plugging capacity of ORG plugging agent under different temperatures, different permeabilities and the same injection pressure was studied by using a self-made selective plugging simulation device. With the increase of core permeability, the water plugging rate and oil plugging rate increased, while the water plugging rate and oil plugging rate were low due to the low permeability core, but all showed good selective water plugging capacity. And the theory of molecular action of cationic polymer adsorption on rock surface was studied in the ORG plugging agent. The plugging mechanism of ORG plugging agent in the rock pore was studied.
